Transient optic neuropathy secondary to MOPP chemotherapy in Hodgkin's disease: report of a case

The authors describe a case of optic neuropathy in a child undergoing MOPP chemotherapy for Hodgkin's disease stage IIISA. Visual acuity improved after substitution of the aforementioned regimen with ABVD chemotherapy, and reached 1 during maintenance therapy with vinblastine. Various neurologic deficits have been ascribed to vincristine, a well-known neurotoxin. This case of optic neuropathy is supposed to be a rare example of involvement of the 2nd cranial nerve due to vinca alkaloids. The absence of neurotoxicity of vinblastine in this case is emphasized.
